I tried a few, now I have these:
https-everywhere
html5 video everywhere
Noscript for some rare js exceptions
Request Policy for redirections
Random agent spoofer for html5 and making tracking harder
self-destructing cookies
ublock origin
And only youtube-dl since the others rely on some activated js at some point.
So this one is similar to donottrack and disconnect?
But with Noscript and RequestPolicy, isn't that enough?
Maybe it's geared towards people who have js on (the "normal" people, I am
tempted to say).
I love the idea of this being a built-in feature though.
